Buy Custom Made Essay Papers on Microorganism Microorganisms are the tiny organisms that cannot be seen by the naked eyes. We have collected some information you can use for your microorganism essay: The nature- the basic approach for the essay could be dealing with the nature of the microorganisms.
You can talk about their size, how they look in the microscope, their habitat, how they function in different environment, where they are found, whether they are plants or animals, and similar other basic nature. In the ecosystem- what is the place of microorganisms in the ecosystem- can also be answered in the paper.
Hidden World of Microorganisms 2. General Classification of Microorganisms 3. Importance in Human Welfare. The microorganisms are very minute in size and constitute the vast and diverse microbial world which occupies every nook and cranny of the Earth, from the deepest depths of the ocean to the highest mountain peaks, living in the water, soil, and air that surrounds us, on and in the food that we eat, on and within our bodies.
Communities of bacteria, archaea, microalgae, protozoans, and micro fungi account for most of the oceanic biomass. Estimates proclaim that there are more bacterial cells in our body than human cells, for convenience, there are 10 14 microorganisms in our colon and trillions more on our hands and in our mouth.
Whitman and his colleagues have given an analysis in exploring the abundance of prokaryotes. This analysis suggested that the total number of living prokaryotic cells is x 10 30 composed of 1. An alternative way to appreciate these figures is that even while accounting for the idea that a prokaryotic cells is typically about 10,fold smaller in volume than a eukaryotic cells, the total amount of prokaryote biomass is still approximately 10, times greater than the amount of human biomass currently present on Earth.
A comparison of the numbers of described species of microorganisms to the estimated numbers highlights the fact that the current description constitutes an almost insignificant number in terms of the inventory of all species currently residing on Earth Table 1. We all know that there are tremendous number of microorganisms on the earth. They are ubiquitous in occurrence, have plasticity in their genome, possess adaptability to varying conditions of environment, enjoy specialties in their life-style and biochemistry, and represent diversity in their mode of nutrition.
Therefore, the microorganisms can be classified in different categories from different viewpoints. Microorganisms can be classified into two categories on the basis of their body organization: Microbes beyond cellular organization, in spite of having the characters of cellular organisms, are completely devoid of any cell structure in their body organization, e. Contrary to it, the cellular microorganisms have their body made up of cells, e.
On the basis of nuclear organization the cellular microbes can further be grouped into two: Prokaryotic microorganisms are those that possess incipient nucleus that lacks nuclear membrane, nucleoplasm and nucleolus archaebacteria, cyanobacteria and eubacteria. In contrast, the eukaryotic microorganisms possess a well-developed nucleus with nuclear membrane, nucleoplasm and nucleolus microalgae, protozoans, slime moulds and micro fungi.
The microorganisms except viruses, viroids, etc. The bacteria and cyanobacteria are monerans; microalgae, protozoans and slime moulds are protistans and; the micro fungi are mycophytans. Bacteria and cyanobacteria belong to domain Bacteria, arcbhacbacteria to domain Archaea, and all eukaryotic microorganisms microalgae, protozoa, slime moulds, fungi belong to domain Eukarya. Photoautotrophs are those that use light-energy to manufacture synthesize their food; photosynthetic microalgae, cyanobacteria, and photosynthetic bacteria are the examples.
Chemoautotrophs are those that use chemical-energy to manufacture their food; the group consists only of bacteria like sulphur bacteria, iron bacteria, nitrifying bacteria, etc. Photoheterotrophs are the microorganisms that use light-energy in obtainment absorption of their food from external environment; purple non-sulphur bacteria are examples. Chemoheterotrophs saprophytic bacteria, symbiotic bacteria, micro fungi, protozoa, and colourless microalgae are those that use chemical-energy in obtainment absorption of their food from external environment.
Microbial growth is affected by temperature of the environment to a great degree. In this respect, the microorganisms can be classified as under. Require sufficiently low temperature for their survival. Grow at elevated temperatures lethal to many others. Certain mesophilic microorganisms are capable of withstanding high temperature, though they do not multiply at these elevated temperatures. They are also called psychroduric or cryoduric.
These are those mesophilic microorganisms that can survive at very low temperatures but do not grow and multiply. On the basis of their distribution in environment, the microorganisms can be classified into three categories: Osmotic concentrations of substrates where upon the microorganisms grow help classifying them as under: Microbiology is as an area of activity having a marked realized as well as potential impact on virtually all domains of human welfare, ranging from food processing, protecting the environment, to human health.
As a result, it now plays a very important role in the employment, production and productivity, trade, economics and economy, human health, and the quality of human life throughout the world.
This is clearly reflected in the emergence of numerous companies throughout the world, including India, and the movement of noted scientists, including Nobel Laureates, to some of these companies.
The total volume of trade in microbiological products is increasing sharply every year, and it is expected to soon become the major contributor to world trade. Many commentators are confident that the 21st century will be the century of microbial biotechnology, just as the 20th century is the era of electronics. The importance of microorganisms in human welfare would become obvious from some selected examples given as follows: Infectious disease caused by microorganisms have been of mankind for centuries and continue to cause highly morbidity and sufferings worldwide.
Disease and death have always attracted the attention of the human mind. The emergence of acquired immunodeficiency syndrome AIDS caused by human immunodeficiency virus HIV as a major modern day scourge with tremendous public health importance has brought into limelight even those diseases which were considered rare in the past.
Applications of microbiology have given medicine the greatest success in the diagnosis prevention, and cure of disease Table 1. Production of variety of antibiotics, e. Many dairy products are manufactured, at least in part, via microbial activity. They include cheese, yogurt, buttermilk, etc. Similarly, sauerkrant, pickles and some sausages also owe their existence to microbial activity.
Even more pervasive in our society are alcoholic beverages which are also based on the activities of yeasts. We know that food spoilage by variety of microorganisms results in immense economic loss every year. The canning, frozen-food, and dried food industries exist to prepare food in such ways that they will not undergo microbial spoilage.
Some microorganisms have long been used as human food, e. More recently, efforts have been made to produce microbial biomass using low cost substrates and use it for human consumption. Since this microbial biomass is rich in protein, it is popularly called single cell protein SCP. SCP can be produced using algae, fungi, yeasts and bacteria. The substrates used for SCP production range from CO 2 used by algae through industry effluents like whey, etc.
Microorganisms play an important role in our life: helps us to digest our food, decompose wastes and participate in various cycles. They.
Short Essay on Micro-Organisms. Article shared by. Soil contains a large number of bacteria and other microbes. Several microbes are harmful to us. They cause disease like cholera, typhoid, polio and leprosy in human beings. Some of these microbes are helpful to us. The nitrogen-fixing bacteria found in the root nodules of leguminous plants.
Microorganisms, which include many different fungi, bacteria, and actinomycetes, are considered the architects of the soil as they have the ability to create a strong ecosystem in the soil. Microorganisms work best in communities to develop the structures for plants. ADVERTISEMENTS: In this essay we will discuss about Microorganisms. After reading this essay you will learn about: 1.
